MACHINE FOR SETTING UP, DRILLING, AND PlNNlNG BICYCLE-FRAMES.

SPECIFICATION forming part of Letters Patent No. 602,623, dated April 19, 1898.

Application filed J 1115' 21', 1 8 97 To all whom it may concern:

Be it known that I, HENRY KELLER, a citizen of the United States, residing at the city of Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Setting Up, Drilling, and Pinning Bicycle-Frames; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had tothe accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

This invention relates to machines for setting up, drilling, and pinning bicycle-frames 5 and it consists, substantially, of the combination in one machine of a drill-press mechanism and a skeleton table mounted upon trunnions, so that it can be turned over, and provided with clamping mechanism adapted to be so adjusted thereon that any sized or shaped bicycle-frame can be clamped therein and firmly held until it is drilled and pinned together ready for brazing. This work has heretofore been done by clamping the frame into a suitable portable jig and then holding it upon the table of a drill-press and moving it about thereon until the necessary holes were drilled therein and then removing the jig with the frame therein from the drillpress table and pinning it together.

In the machine I have invented I dispense entirely with the ordinary portable jig and make a drill-press table in such shape that it operates as a bicycle-frame jig which can be adjusted to fit any sized or shaped frame, and this table, being mounted upon trunnions, can be reversed, so as to allow the drill to operate on both sides of the frame, and to adapt the drill mechanism to be operated at any point on the frame desired it is mounted upon a radially-swinging arm adapted to swing over the entire table, and as the drill mechanism moves freely in and out on said arm all parts of a bicycle-frame clamped on said table can be readily reached and operated upon by said drill, and by swinging the drill-arm to one side the table with the frame thereon can be turned over on its trunnions bottom side thereof.

up and the drill operated thereon through openings in the table for that purpose. These and other features of my invention are hereinafter more fully set forth and described, and illustrated in the accompanying drawings, in which Figure 1 is a perspective View of a machine embodying myinvention, showing a bicycleframe clamped thereon. Fig. 2 is a top or plan view of the same. Fig. 3 is a top or plan view of the table portion of the machine, showing the adjusting and clamping mechanism thereon.

In the construction of my invention thus illustrated the drill-press portion thereof consists, substantially, of a standard A, secured to a suitable base, a column A, mounted in said standard A, a radially-swinging arm B, mounted on said column A, a frame 13, adapted to be moved in and outon said arm and carrying a vertically-operating drill-stock b, a radially-swinging arm 0, mounted on the column A above the arm B, a like'arm O, one end of which is pivoted to the end of the arm 0 and the other around the stem of the drill-stock Z), and a double idler-pulley D, mounted on a bearing d, concentric with the pintle, pivoting the ends of the arms 0 and O together. On the column A, just above the arm 0, there is loosely mounted a double pulley E E, the pulley E receiving the driving-belt F, which passes down over idler-pulleys ff to and around a driving-pulley G, mounted in bearings g on the back of the standard A, by means whereof the motive power is communicated to the pulley E, and thence by belt 6 to the idler-pulley D, from whence power is communicated by means of a belt 6 to a pulley D, mounted on the stem of the drill-stock b and connected therewith by means of a spline and groove cl, so that the stem of the drill-stock will move freely up and down therein.

In front of the standard A there is a table H, supported on trunnions h 7t, mounted in posts I I. This table H is preferably made substantially in the shape of a Greek cross, the arms H H of this table, towhich the trunnion-bearings are secured, being, however, slightly longer than the arms H and H These arms and the central part of the table are centrally cut away, so that when the table is turned over on its trunnions bottom side up, so as to drill joints on the opposite side of a bicycle-frame clamped thereon, the drill will pass through said openings, so that all necessary parts of the frame can be operated upon thereby.

The trunnions h hare secured to arms h h, attached to the ends H and H which arms extend sufficiently above the top of the table H that the trunnions h h in the ends thereof are substantially on a level with a bicycleframe clamped upon said table, so that when the table is reversed and turned over on its trunnions the bicycle-frame clamped thereon will be substantially the same distance below the drill as it is when the table H is right side up.

In each of the arms 11, H H and H of the 'table H are cut longitudinal slots J J, and

across the ends of these arms are secured transverse plates K, K, K and K by means of bolts 70, passing therethrough and through the slots J J, whereby the plates K K, 850., can be adjusted in and out as desired. These plates K, K, K and K are provided with longitudinal slots 7t, in which clamping mechanism is adj ustably securedviz., on the plate K are two clamp-screw heads L and L, provided with clamping-screws [and Z, adapted to engage the upper and lower ends of the steering-post of a bicycle-fram e, as illustrated in Figs. 1 and 2. On the plate K is a clamping-head M, provided with a removable piece m, adapted to engage the forks at the rear of a bicycle-frame, as illustrated in Figs. 1 and 2. On the plate K isa double clamping-head N, provided with a clamping-screw 'n and bearing 01, adapted to engage the ends of the crank-shaft bearing of a bicycle-frame, as illustrated in Fig. 1, and on the plate K is a clamping-head 0, provided with a clampingscrew 0, adapted to engage the upper end of the seat-post of a bicycle-frame, as illustrated in Figs. 1 and 2. All of these clamping-heads being adjustable in the slots 70 in said plates and the plates being adjustable on the table H, it is obvious that the plates and clamps can readily be adjusted to fit any sized and shaped bicycle-frame desired, which may be firmly clamped together and held while being drilled and pinned ready for brazing.

From the foregoing description the operation of this invention is so obvious that further description thereof is deemed unnecessary. Therefore lVhat I claim as new, and desire to secure by LettersvPatent of the United States, is

1. In a machine for setting up, drilling and pinning bicycle-frames, the combination of a radial drill mechanism, and a drill table mounted upon trunnions secured to arms extending above the top of the table, plates adjustably mounted on the sides of said table,
